The invention relates to new and useful improvements in easy openingcontainers, and more particularly to a container of the rip strip typewherein the strip iswound on to a 5 key, and thus the metal severed orreleasing the end from the body of the container. In this type ofcontainer it is a common expedient to secure the key to the conta nerend by soldering or welding, and when 1t is desired to use the key it istorn loose from the end either by a rupture of the solder or the ruptureof the metal of the key itself.

An object of the invention is to 'provlde a key which is so shaped thatwhen it re attached to the end the shank portion may he adjacent to andsubstantially parallel w th the end, while parts of the handle portionare spaced away from the end to permit the fingers to be insertedbeneath the handle por- 20 tion for lifting the key to rupture itsconnection to the end.

The invention is directed to a key attachment for an easy openingcontainer of the rip strip type. The key is fixedly secured to the rcontainer end either by soldering or welding,

and when it is desired to use the key for removing, the rip strip istorn loose from the end. When the key is attached to the container endthe shankof the key is substantially parallel with the end. If thehandle lies in the plane of the shank it is diflicult to insert thefingers beneath the handle for lifting the key, as the key when attachedlies close to the end so as to be housed within the depression formed inthe end to facilitate double seaming. The present invention is directedto a. shaping of the key so. that the handle portion or parts thereofmay be spaced away from the end while the shank is adjacent to andsubstantially parallel with the end. This provides a ready means'for theinsertion of the fingers beneath the handle for lifting the key torupture its connection to the end.

Referring more'in detail to the drawing, in Figure 2 a portion of acontainer is shown which consists of the body 1 to which an end 2 isattached by means of a double seam 3. This body portion is scored alongthe lines 4, 4 to form a rip strip 5, and the rip Strip is provided witha projecting tongue 6 onto which a key is slipped so that the strip maybe wound onto the key, and thus forcibly torn from the body of thecontainer. The invention is directed to the shaping of the key. As shownin Figures 1 and 2 the key includes a shankportion 7 which is providedwith a slot 8 extending lengthwise of the shank portion, and the tongue6 is inserted in this slot when the key is used for winding the ripstrip thereon. The key as shown is attached to the end by soldering thesame at 9 to a raised portion on theend. Instead of soldering the key tothe end it may be 7 welded thereto or secured in any way so that 7 it isfixedly attached to the end and becomes a part of the container 'unitwhen shipped. The attaching means or the key itself adjacent theattaching means is so constructed that it may be ruptured when the keyis forcibly lifted at the outer end thereof and moved away from thecontainer. This has been accomplished by using a solder bond which canbe ruptured, and ithas also been accomplished by scoring the'key at apoint adjacent the welding so that the shank of the key itself may beruptured. Other ways may be utilized for fixedly attaching the key so ithat when it is lifted it may be torn loose from the end. The key isbent into a loop The portion of the shank beginning at the point 11 isbent upwardly at 12. This up wardly inclined portion of the shank issubstantially beneath the plane of the outer edge of the double seam sothat the key is practically housed within the recess made in the end tofacilitate double seaming. The handle portion 10 is bent downwardly sothat the outer bar 13 makes contact with the face of the can end. Thisaids in thepositioning of the key for the initial securing of the sameto the cover and it also prevents pressure applied to the key handlefrom straining the solder bond and breaking the same. By thisconstruction of key the fingers may be readily inserted beneath theraised portion of the obtained on the key for lifting the same away fromthe end and thus rupturing the solder bond or the key adjacent the bond.In Figures 3, 4 and 5 the shank 7 of the key is constructed precisely asin Figures 1 and 2, and the key is attached to the end in the same way.In this form of the key the shank all theway to the handle lies in asingle plane. The handle indicated at 15 is made in loop form and theends 16, 16 are raised, and this is accomplished by curving the bars ofthe handle upwardly from the center portion thereof toward the outerends as shown in Figure 5. The fingers may be readily inserted beneaththese ends of the handle for a firm grip on the key for lifting thesame.

In Figures 6, 7, and 8 the shank 7 of the key is constructed in the samemanner as in Fig ures 1 and 2. The shank 1 L inclines upwardvtures. 7

the end no particular position of the key relative to the end isnecessary, except that the end of the shank which is to be secured tothe end must be placed at the desired point for attachment. Noconstruction of the end is necessary other than the usual depressionformed in the end for facilitating double seaming. The key lies in thisdepression and is substantially housed therein and thus protected, andatthe same time it maybe readily grasped and lifted, and the attachingmeans ruptured so that the key may be used for opening-the container.

Having thus described the invention, what we claim as new and desire tosecure by Letters Patent, is handle and the shank, and thus a firm gripThe combination of ahermetically sealed container having a rip stripwhereby the container may be opened and a container "end hermeticallysecuredto the container adjaend of the key being free from depressions,

said key having the shank portion thereof disposed adjacent to andsubstantially parallel with said container end and having parts thereofadjacent the free end of the key bent away from the container end andspaced therefrom so thatthe fingers may be inserted beneath said bentportions for lifting the key to rupture its connections to the end.

In testimony whereof,we aifix our signa- "FRED-A. PRAHL.

ly as in Figure 2, and the handle portion lies substantially in aninclined plane containing this inclined shank let. The handle portion 17is made in loop form and the ends 18, 18 are placed closer tothe endthan the central portion of the handle. This is done by arching theouter bar of the handle member as shown in Figure 8. By this arrangementthe finger may be readily inserted beneath the arched portion ofthehandle and a firm grip From the above it will be apparent that wehave provided a construction of key whereby it maybe attached to a canend by soldering or welding so that the shank of the key is adjacent andsubstantially parallel with the end. The key handle, however, has partsthereof shaped so that they are spaced from the end to permit theinsertion of the fingers for lifting the key to rupture its attachmentto the end.
